How do you separate gold from other substances

May 27, 2009· 1). One way is by 'panning'; since gold is heavier than most other substances, you can swirl water just fast enough that the gold stays in the pan while the other substances wash out. Or, 2). You can put everything into an acid that dissolves other substances and doesn't dissolve gold. Or, 3).

Extracting Gold HowStuffWorks

Feb 23, 2009· This causes gold to collect on the negative terminals. ­Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers

How to Separate Silver & Gold by Cementation

Older processes explaining how to go about separating silver from gold by cementation were carried on practically in two ways, the first by heating gold for a long time with a mixture which evolved nitric acid on heating, and an absorbent into which any fusible salts ran; the mixture in the second method contained common salt as an essential ingredient, and some material which would assist in

Processing, smelting and refining gold World Gold Council

When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.

Gold Properties, occurrences, and uses Britannica

Among the relatively few gold compounds of practical importance are gold(I) chloride, AuCl; gold(III) chloride, AuCl 3; and chlorauric acid, HAuCl 4. In the first compound, gold is in the +1 oxidation state, and in the latter two, the +3 state. All three compounds are involved in the electrolytic refining of gold.

DK Science: Separating Mixtures Fact Monster

Gold particles are heavier than the other particles, so they settle to the bottom of the pan. The lighter particles stay suspended in the water, and are decanted (poured off). This technique of panning for gold is called decanting. Cream is also separated from milk by decanting

How to Take the Impurities out of Gold LEAFtv

Set the gold ore and a small quantity of lead in a cupel. Place the cupel in a blast furnace. Heat the mixture until the lead and gold ore liquefy. The blast furnace batters the cupel with hot air. The lead combines with other metals and forms oxide compounds that separate from the gold. This process works best with small quantities of gold ore.
